I needed t get from HK to New Delhi very quickly to close a very big contract with a giant Indian conglomerate. My HK staff told their local travel agent 'any airline, first flight out of HK. Departed HK very quickly on Air India.
Half way suddenly a family sitting same row as me got on the floor and pulled out a small pump up stove and got it working and put a small pot on the stove, water and veg.
Several people reacted in horror and the stewards came quickly ordering them to put the fire out and give the stove to the stewards.
But other nearby passengers told the stewards and the upset passengers to back off 'leave them alone, they have to eat'.
Stewards did confiscate the stove, no announcements made, and on landing nothing more was said.
Another western passenger sitting near me said 'I've seen this before, don't worry about it'.
Several days later I returned to HK, not on Air India.
